Hi all, i have a Broncsonik tv, when is plugged to the wall (120ac)i
get 127Vac at the end of the cable, inside the tv of course. The second
i turned the set on, the voltage drops to 83 volts, can any one tell me
why, what should i be looking for? I´ve check all components in the PS
area and everything SEEMS to be ok. Any ideas?.
Thnx.

bad wiring?

Is the voltage at the wall socket still 120V (nominal)?

Are you sure you're referencing to neutral and not safety ground
(setting aside for a moment the safety ramifications if they're
different by 20 volts)?

Be careful; I sense you may not be qualified for this kind of thing.

Is the set working? If not, what other symptoms are present? If it is
working, the floating ground may be your apparent problem.

My first guess is that at the breaker/fuse box, the neutral connection to
the power ground has come loose. If this is the case, the voltage may be
high on some outlets and low on others, depending on what things are tuned
on or off. This could damage equipment and burn-out lamps.
